First you calculate the area of the big rectangle (ignoring the small one the bottom):
A1 = 10 x 6 = 60.
next you calculate the small one:
A2 = 2 x 2 = 4
Now you subtract the small one from the big one and you get:
Area of the figure = A1 - A2 = 60 - 4 = 56
In order to answer, I would first need to know Jana's speed, not that she biked at a constant rate.
40 x 6 + 16 =
= 240 + 16 =
= 256
256 / 40 = 6 with a remainder of 16
Hope I helped.
